Details

I'm using rspack to build my React project, but the build fails due to a regex used in one of the third-party component. And I created an empty project with npm create rspack@latest , and the same issue occurs when using the following regex.

Panic occurred at runtime. Please file an issue on GitHub with the backtrace below: https://github.com/web-infra-dev/rspack/issues
Message: should an valid regexp: Syntax(
